ChiralSU(3)⊗SU(3)Three-Point Functions: Single-Particle Approximation

Abstract

We approximate the three-point functions constructed previously by using a single-particle approximation to all propagators and assuming that the primitive three-point functions are slowly varying functions of the momenta. We use the available data on strong and weak decays of spin-one and spin-zero mesons to compute the values of the parameters introduced in our model, with special reference to $K_{l3\mathrm{}}$ decay.
